I wrote a function that queries the a database to find out what a specific users role(s) once logged in using their user ID from the session. However when I went to test it. It output the correct data but it was not in the right place. For example when I log in with one of my users whos username is "Fred12" it says "Hello there fred12 your roles are the above it it has the users role in one long string. See attached screenshot . The roles should be on the same line as everything else. Below I included the code for both my function and the page which the text in question appears. I have posted other questions using this same code as I had some other issues before getting to this point.

I am running Tomcat 9 on an Ubuntu 20.04 OS using OpenJDK 64-Bit Server VM (build 25.275-b01, mixed mode). When I try to gather diagnostics info using jstat, jstack, etc, I see PID not found. jps also cannot identify the Tomcat process id.

I have checked several posts like one, two, three, four, etc, but none of the answers given in these helped me to solve my problem!

Even though I am passing the username with which the Tomcat process is running, jstat cannot find that process: sudo -u tomcat jstat -gc 476174 5000

In case it matters:

1. I can see that the Tomcat process is started with -Djava.io.tmpdir=/tmp This folder is owned by root user but has full permissions(777) enabled.
2. When the Tomcat process is started, I can see a folder with name systemd-private-e6d8b5dc224848f8a64a3e943ac2e9c4-tomcat9.service-UH5knj (the last few chars after service- change every time the process is restarted) getting created with owner as root (probably because I start tomcat service using sudo service tomcat9 start) and this folder has permission of rwx------.

Any hints on how to solve this issue?

Thanks, Shobhana

I am creating a deploy for OpenMage e-commerce here: https://github.com/ProxiBlue/openmage-cluster

In the creation settings dialog, I want to prepopulate the TIMEZONE, LOCALES and CURRENCY from a list generated by a PHP script.

Relevant parts are here:

• Generated prepopulate data: https://github.com/ProxiBlue/openmage-cluster/blob/main/settings/populate.txt
• Script I use to make that: https://github.com/ProxiBlue/openmage-cluster/blob/main/scripts/settings_generate.php
• and then the manifest: https://github.com/ProxiBlue/openmage-cluster/blob/main/manifest.jps#L31

I pinged Jelastic support and they gave me this format to use to make the prepopulate:

I am adding liveness probe and readiness probe using Exec probe.
My config looks like this:

I was trying to parse an API response with Scrapy and JSON but it's generating me an error json.decoder.JSONDecodeError:

I tried all the Japanese encoding types from here but none worked. Hope there is a solution from you guys.

Below is my code:

I have written a simple map reduce job to perform KMeans clustering on some points.

However, when running the following command on Windows 10 cmd:

I'm using IntelliJ for a Spring Boot application made with the Spring Boot Initializr. Added are two dependency's: Spring Web and REST Repositories. Now that I try to build the main class, I get an error saying:

Could not initialize class org.jetbrains.jps.builders.JpsBuildBundle

The configuration is the one given by IntelliJ and I tried updating my JDK to version 16 but sadly it didn't work.

Also I'm working on a MacBook Pro with the M1 chip (don't know if it could have anything to do with the problem, but couldn't hurt mentioning it).

I'm writing a console app that will run in Linux and Windows systems. This app will mainly run on JRE 1.8 environments.

In my code, it needs to get a list of Java processes that run on the host running my application. I have read the posts about jps, which come as a part of JDK, but not JRE, and also it's a separate executable.

My question is, is there any java library that I can use, to list (and ideally also kill some of) the running Java processes? Preferably, I would not want to hassle of calling jps executable with sth like Runtime.exec().

Thanks in advance, for any suggestions.

Following these two tutorials: i.e tutorial 1 and tutorial 2, I was able to set up HBase cluster in fully-distributed mode. Initially the cluster seems to work okay.

The 'jps' output in HMaster/ Name node

The jps output in DataNodes/ RegionServers

Nevertheless, when every I try to execute hbase shell, it seems that the HBase processors are interrupted due to some Zookeeper error. The error is pasted below:
